Catch Trophy Trout in Murky Yellowstone Waters

Catch Trophy Trout in Murky Yellowstone Waters

The Yellowstone Angler reports that while current river conditions are murky with a flow of 4,110 CFS, the recent influx of moisture has provided a much-needed boost to the regional snowpack. Although clarity remains variable due to runoff from the Shields and Lamar, the report highlights a productive window for anglers willing to navigate the “chocolate milk” conditions to target trophy-sized trout in the 18 to 24-inch class. By monitoring discharge rates and focusing on streamer play or midges during calm stretches, fishers can capitalize on the pre-runoff activity before the river potentially swells further.

Here’s the latest, as of April 13, 2026, rom Yellowstone Angler:

CFS (and clarity) will be variable the next couple weeks. We are thankful for the moisture and snow the past few days as things were starting to look thin up there for early April.  Snow pack on the Upper Yellowstone Basin as of Wednesday 4/8 was 82%. 

Keep an eye on the CFS and try to catch a dropping river if you can, or hopefully at least fish the river when it is olive or green vs a brown. Also keep an eye on the Sheild’s CFS as that has a tendency to make the lower river extra brown with mud this time of year. Obviously ditto that for the Lamar CFS up high. The river is still pretty low, so if it’s muddy and you can’t see, it’s best to avoid the shallows or hitting any obstructions or jagged rocks just under the surface. 

If the winds do calm down midges have been out in full force (in specific areas). Spring Baetis are bound to pop so keep an eye out for them as well as March Browns, (particularly down low).  Alsbut from flipping rocks, baetis nymphs are certainly brewing.

Many anglers have been fishing streamers and catching some nice fish in the 18-20″ class. We’ve heard of a couple 2 footers caught already as well.  From now until runoff is a great time to target larger fish, someone is bound to catch one and it will likely go to those who in the work – might as well be you!
